ある。Detailed Description of the Invention (Industrial Field of Application) The present invention performs cross-flow filtration of slurry and liquid. In the case of a liquid, it relates to a filtration concentrator that can be used as a filtration concentrator.

、あるいは遠心分離器などが知られている。(Prior art) Conventionally, clarification filters include cross-flow filters that use cylindrical porous tubes to cross-flow filter slurry into the porous tubes, and concentrators include filter presses and centrifugal separation. It is known for its utensils.
（発明が解決しようとする問題点）
上述した濾過器のうち前者の従来のクロスフロー濾過器
は、円筒状多孔質管の濾過層表面にスラリー液中の固形
粒子が堆積すると濾材抵抗が大きくなり濾過速度が低下
するため、濾過層表面に固形粒子がケーキとして堆積し
ないようにスラリー液を高速で流す必要がありその結果
大きな動力費を要する欠点があった。(Problems to be Solved by the Invention) Among the above-mentioned filters, in the former conventional cross-flow filter, when solid particles in the slurry liquid accumulate on the surface of the filtration layer of the cylindrical porous tube, the resistance of the filter medium increases. Since the filtration speed decreases, it is necessary to flow the slurry liquid at a high speed so that solid particles do not accumulate as a cake on the surface of the filtration layer, resulting in a disadvantage that large power costs are required.
また、濃縮器としての従来のフィルタープレスはバッチ
運転であること濾材の閉塞が早く逆洗再生を頻繁に行う
必要があることなどにより、メンテンスの点、省エネの

となるばかりか分離に限界があり分離液中に微小粒子を
少なからず含む為、分離効率が悪く高価な粒子、あるい
は公害の点で問題があるなどの欠点があった。In addition, conventional filter presses used as concentrators have problems in terms of maintenance and energy saving, as they operate in batches and require frequent backwashing and regeneration because the filter media gets clogged quickly. Not only does this require a large amount of power, but it also has limitations in terms of separation, and the separation liquid contains quite a few small particles, which has disadvantages such as poor separation efficiency, expensive particles, and problems with pollution. .
本発明の目的は上述した不具合を解消して、スラリー液

濾過濃縮器を提供しようとするものである。The purpose of the present invention is to eliminate the above-mentioned problems and provide a filtration concentrator that can achieve sufficient filtration speed and separation efficiency even when the flow rate of the slurry liquid is slow, and as a result, can achieve energy savings in terms of the power used, etc. That is.

ある。(Means for Solving the Problems) The filtration concentrator of the present invention comprises: an outer cylinder having a filtrate discharge hole; a cylindrical porous tube installed concentrically inside the nuclear outer cylinder; a vortex-generating cylindrical porous tube installed concentrically inside the shaped porous tube; and a slurry provided at each end between the cylindrical porous tube and the vortex-generating cylindrical porous tube. Consists of a liquid supply hole and a slurry liquid discharge hole,
While rotating the vortex generating cylindrical porous tube, the slurry liquid to be filtered is supplied from the slurry liquid supply hole, and the supplied slurry liquid is transferred to the cylindrical porous tube and the vortex generating cylindrical porous tube. The filtrate is filtered through the drain hole and the filtrate is discharged to the outside from the discharge hole, and the slurry liquid after filtration is discharged from the slurry discharge hole.

So-called cross-flow filtration is achieved in which the slurry liquid is filtered using only the resistance of the filter medium without causing any turbulence.

This is a filter that performs cross-flow filtration by constantly cleaning the surface, and compared to conventional cross-flow filters, there is no need to flow the slurry liquid at high speeds, and in other words, the flow rate is small.In other words, it is possible to achieve high filtration speed with low power costs. can be obtained. In addition, when used as a filtration concentrator, not only can it be operated continuously, but if a filter material suitable for the slurry liquid is used, it can be separated with a separation efficiency of 100%, and furthermore, filtration and concentration can be performed with a small power cost. It is possible to achieve an energy-saving, high-precision, high-speed filter that has greatly improved the drawbacks of the above.
